please configure the postgresql binary path in the preferences dialog - how do I do this?

I installed PostgreSQL because I need to restore a large .backup file I received for upload to another platform (it's 38 million rows which was apparently too large for the person to export any other way). When I try to "restore" in pgAdmin 4 I get the message: Please configure the PostgreSQL Binary Path in the Preferences dialog.

Is this just the path to the PostgreSQL folder? I can't find documentation on this on the PostgreSQL site. All I can find is:

Use the fields in the Binary paths node to specify paths to the PostgreSQL binary utilities and EnterpriseDB Postgres Advanced Server binary utilities.Is there an easier way to restore the database other than through pgAdmin?
